Our Network
Our Datacenters:
 
   Shared, Managed & Semi-Managed Datacenter

Our servers are located in the state of the art BURST.net datacenter.

Environment:
Precision-controlled raised floor air conditioning systems protect and cool mission-critical servers and equipment in the Network Operations Center. The facility is controlled by dual 30-Ton APC™/Airflow™ triple-compressor redundant systems. These systems provide a virtually dust-free and particle-free computing environment, with temperature, humidity, and air-quality regulation.

Security: Restricted access to the Network Operations Center is monitored by qualified personnel 24 hours a day, every day. Visitors and clientele are only allowed on-site if escorted by Network Operations Center staff. The entire Network Operations Center is monitored, ensuring prompt response and thorough coverage to fire or security alarms. We supply all our Network Operations Center customers with advanced firewall, encryption, intrusion detection and other security measures. Navigator Internet Solutions, Inc.™ maintains a full digital video surveillance system of the Network Operations Center, with full on-site and off-site recording.

Failsafe Power Supply: Our Network Operations Center currently has 800amps 480V (3200amps 110V) 3-Phase power currently available from PP&L™ (Pennsylvania Power & Electric). The facility is currently backed up and protected by a 160KVA Powerware™ 9135 facility-wide UPS (Uninterruptible Power Supply) system. In a very rare case of utility outage, our Cummins™ 250KW diesel generator starts automatically, taking over for the UPS systems and supplying all necessary power for the facility. The generator interfaces to the power grid thru a Cutler-Hammer™ automatic transfer panel. The generator is powered by a 500 gallon fuel tank, capable of running without refueling for approximately 80 hours. An APC Silcom™ (http://www.apc.com) 500KVA Enterprise UPS, and further generator capacity, is scheduled for install in early 2004.

Backup Systems: Navigator Internet Solutions, Inc. automatically provides backup data services to all shared hosting solutions clientele. Services are also optionally available to all dedicated and co-location clientele. Navigator Internet Solutions, Inc.™ utilizes backup hard drives on each individual server to store backups. Linux systems store zipped copies of server system files and client data files, for simple server rebuilding. Windows™ NT/2000 servers store full image backups (identical copy of operating system and data at time of backup), for full system restoration. Off-server and off-site backup services are available as well.

24x7x365 Monitoring: The Network Operations Center uses industry-standard SNMP (Simple Network Management Protocol) and provides round-the-clock monitoring of all hardware, including routers, switches, UPS systems, and servers. The Network Operations Center also monitors power, environmental factors (such as temperature and humidity), generator status, and network connectivity. All critical services/ports can be monitored, including FTP, HTTP, SMTP, HTTPS, SSH, TELNET, and POP3. We provide network monitoring of the Local Area Network, Internet connectivity (all routers, switches, and wiring), and the Internet backbone via MRTG. Our close and constant communication with our upstream backbone providers ensures that our customers have constant access to high-performance Internet connections. Failure on any monitoring service results in audible alarms, LAN messages, and alerting our staff paging system. Navigator Internet Solutions, Inc.™ offers remote cold boot hardware for dedicated server and co-location clients, with private, password protected, web based access.

Hardware: The Network Operations Center utilizes ONLY top name brand hardware. The network is centered on a Cisco™ GSR12000 Border Routers, and Cisco 7206VXR Core Routers, connecting via Gigabit Ethernet to the Hewlett Packard™ Procurve™ 4108GL & Cisco™ Catalyst™ primary switches. Hewlett Packard™ Procurve™ managed switches comprise the power and stability of the network, operating at 100mbps switched ethernet speeds. Hardware utilized in the facility is comprised of name brands, including the following: Intel™, Asus™, Abit™, AMD™, 3Com™, Hewlett Packard™, Adaptec™, Cisco™, Tekram™, Kingston™, Micron™, Crucial™, IBM™, Maxtor™, Western-Digital™, Seagate™, Quantum™, Fujitsu™, Realtec™, Belkin™, & Lucent™. APC™, Tripp-Lite™, Compaq™, & Liebert™ UPS Systems provide the power backups, along with a Cummins™ generator system. Facility monitoring is provided by a Panasonic™ WD-500 Digital Video System over Sony™ & Panasonic™ CCTV cameras.

Software: The Network Operations Center utilizes the Red Hat™ Linux operating system on the majority of servers present. Red Hat™ Linux is a highly configurable system, and well known for speed and stability. Red Hat™ Linux servers have been documented to remain operating for up to one year at a time without even requiring a reboot. The Apache™ Web Server nicely compliments the Red Hat™ Linux Operating System. The majority of remaining servers operate on the Microsoft™ Windows™ NT/2000/2003 operating systems, with Internet Information Server™ Web Server. Microsoft™ Windows™ NT/2000/2003 provides a system that simplifies database, application, and visual effect programming. Navigator Internet Solutions, Inc.™ also supports FreeBSD™, Mandrake™, Slackware™, Turbo Linux™, & Debian Linux™.

Connectivity: The network is connected via Gigabit fiber connections to Verizon™ (Formerly Bell Atlantic PA), PPL Telcom™, (a sub-division of Pennsylvania Power & Electric™ - PPL™) and Commonwealth Telephone™ (CTSI™), NorthEast PA's 2nd largest Telco. The network currently connects BurstNET POPs (Points of Presence) in Scranton/Wilkes-Barre, Philadelphia, & New York City, with others to be completed shortly. Navigator Internet Solutions, Inc.™ transit is provided via Gigabit Ethernet (1000mbps) from Verio™ (http://www.verio.com), Global Crossing™ (http://www.glbx.com), Cogent™ (http://www.cogentco.com), and XO™ Communications (http://www.xo.com). For redundancy, currently running BGP4 (border gateway routing protocol) to maintain the speed and uptime. If one backbone line goes down, it will balance the load to the other(s). If one line gets congested, it will load balance the traffic. Navigator Internet Solutions, Inc.™ is currently negotiating with major backbone providers to open POPs in the Navigator Internet Solutions, Inc.™ Scranton PA facility. Navigator Internet Solutions, Inc.™ is currently the only major data center/co-lo facility within 60-75 miles of the Tier-3 Scranton/Wilkes-Barre PA USA Metro Area.


 
   Uptime Servers Datacenter

The Navigator Internet Solutions, Inc. network architecture is a complete Cisco product and is a Cisco Certified Network. We utilize fully redundant Cisco 7500 (redundant routers and redundant cards within the router) at the core and state of the art 3550 L3 switch / routers as border routers. To further maximize redundancy we utilize distributed 2924 XL EN switches to ensure that single chassis failure will have minimum downtime effects on our servers – unlike many of our competition who aggregate hundreds of servers in a single chassis based switch like the 6500 or 5500 which if it fails its cpu or power – it takes down many customers. This approach gives us maximum power failure protection and switch failure protection to distribute the load and risk.

We also utilize VLANS to prevent customer IP space hijacking and conflicts. By keeping our network as flat as possible – we minimize route convergence and latency in the backbone and speed the packets to the best provider through BGP4 on the core.

Our network is fully meshed and redundant with 4 backbone providers. Our current network consists of a gigabit (1000mbit) to Abovenet, a gigabit to Williams, a gigabit to Aleron and a gigabit to Allegiance. By having providers with a larger burst capacity we are able to handle DoS attacks better than many of our competitors that have chosen many smaller pipes. This is because a DoS attack will many times concentrate itself on one inbound or outbound connection and can swamp it if it is only a 100 mbit or an oc3. We do not provision less than GIG circuits on the backbone any more. It also allows us plenty of room to fail back and forth from provider to provider without regards to where the traffic is going to prefer since any one of our links has far sufficient size to handle all of our traffic.

We actively monitor our routers for key factors including temperature, cpu and memory utilization and monitor our connections for transit latency and uptime. We are notified immediately in the event of a process going out of tolerance or an outage through our automated systems which allows us to respond quickly with corrective action.

We also monitor all our servers in the data center for uptime and immediately notified in the event of an outage on the server.
